Mitosis - exam practice

The statements describe events during the mitotic cell cycle:

1 - chromosomes migrate to opposite poles of the cell

2 - chromosomes arrange themselves at the equator of the cell

3 - chromosomes condense and the nuclear membrane disappears

4 - centromeres divide

What is the correct order of three of these events in the mitotic cell cycle?

The diagram below shows a cell during cell division. The diploid number of this cell is three.

In which phase of cell division is the cell in the diagram above?

What occurs in anaphase of mitosis?

Which is always true of cytokinesis?

1 - cell organelles replicate

2 - cell organelles are divided between two cells

3 - nuclear envelope reforms

What occurs during metaphase of mitosis?

Some chemicals, used to stop tumour growth, work by preventing the DNA double helix from uncoiling and separating.

During which stage of the cell cycle would they act?

Which processes occur by mitosis?

1 - cloning of plasma cells

2 - gamete production

3 - replacing damaged cells

During which phase of the cell cycle does DNA replication take place?

What is the correct sequence of stages in the mitotic cell cycle?

Embryonic stem cells can be used in cell replacement therapies.

Embryonic stem cells can differentiate into any type of body cell but cannot form a whole organism.

What is the type of stem cell being described?

Which statement is not true about adult stem cells?

Which statement correctly explains why meristems can differentiate into xylem vessels in plant stems?

Rheumatoid arthritis is a long-term condition that causes pain, swelling, and stiffness in the joints.

What explains why stem cells are a potential source of treatment for rheumatoid arthritis?
